Objective To study the early out-of-bed activities of patients after Mako robotic-assisted total hip arthroplasty.Methods We prospectively included inpatients planned to undergo primary unilateral total hip arthroplasty in the Department of Orthopaedics of the First Affiliated Hospital of Chongqing Medical University from April to July 2020. Using a randomized numerical table, the patients were divided into trial group to undergo robotic-assisted total hip arthroplasty and control group to undergo traditional total hip arthroplasty, and both groups received the same nursing measures and instructions for training to get out of bed after surgery. Postoperative active pain (assessed with Visual Analogue Scale), the proportion of patients willing to get out of bed within 24 h after surgery, the time and duration for the first out of bed activity, the proportion of patients with a walking distance ≥5 m for first activity, and the level of activity in the first 3 d after surgery between the two groups were compared.Results A total of 38 patients were included in this study, with 17 patients in the trial group and 21 patients in the control group. There was no statistical significance in the baseline demographics between the two groups (P>0.05). There were statistically significant differences in postoperative 6-hour and 24-hour Visual Analogue Scale scores between the two groups (P<0.05). Two hours after oral administration of perioperative energy preparations on the day of surgery, the proportion of patients who were willing to get out of bed early in the trial group was higher than that in the control group (100.0% vs. 57.1%, P<0.05). The first time to get out of bed [(4.39±0.17) vs. (8.74±4.70) h], the duration of getting out of bed [(10.89±3.60) vs. (8.37±3.31) h], and the proportion of patients with a walking distance ≥5 m for first activity (94.1% vs. 61.9%) were better than those of the control group (P<0.05). There were statistically significant differences between the trial group and the control group in the average level in the first 3 days after surgery, postoperative first-day level, and postoperative second-day level of getting out of bed (P<0.05). There were no falls, dislocation of the prosthesis, fractures around the prosthesis, or deep vein thrombosis in the two groups of patients during their hospitalization.Conclusion The precise surgery method with the help of Mako orthopedic robot-assisted system can help promote patients to get out of bed early after surgery, and can providea reference for how to improve the rehabilitation of patients after traditional total hip replacement in the future.
